Previous versions
Version 1.0 (NS-CXDC1-V1)
Version 6.2 or 6.5
The only function available was simulated
testing of PT screen operations on a per-
sonal computer.
Symbol names, addresses, and comments
were entered in symbol tables. Then the
required symbols were selected from the
symbol tables when creating screens.
Not supported.
The following two types of data transfers
are possible between CX-Designer (run-
ning on a personal computer) and a PT:
• Data transfers with the PT.
• With data transfers using a Memory Card,
data can be uploaded and downloaded by
any user.
Any of five levels of passwords could be set
for each functional object. A dialog box ask-
ing for the password was displayed each
time an attempt was made to use a func-
tional object for which a password had
been set, and the object could not be used
unless the password was input.
Not available.
New version
Version 2.0 (NS-CXDC1-V2)
Version 6.6
Using a personal computer, a virtual PT
can be connected to a virtual PLC (CX-
Simulator) or to an actual PLC, and the
operation of the entire PT-PLC system can
be simulated. This makes it possible to
reduce the total time involved in debugging.
Symbol names and comments can be input
for symbol tables with no addresses. This
allows screens to be created using symbol
names without inputting addresses. Enter-
ing symbols in screen designs without
addresses makes it possible to reduce the
total time involved in design.
It is now possible to connect OMRON NS-
series PTs to Mitsubishi FX-series PLCs,
A-series PLCs, and Siemens S7-series
PLCs.
A password can now be set for creating
data. When data with a set password is
transferred to a PT, the password is then
required in order to upload the data. This
prevents users who do not know the pass-
word from obtaining that data from the PT.
In addition, a password can be required to
transfer data to the PT. This prevents data
from being accidentally overwritten.
Once a user inputs the password to use a
functional object for which a password has
been set, the password does not have to be
input again as long as the user continues
using only functional objects for which
lower level passwords have been set. Func-
tional objects with a higher-level password
cannot be manipulated. (A warning mes-
sage will be displayed if an attempt is
made.) This makes it possible to create
applications that permit only the necessary
operations by users who have entered
passwords, and thus helps prevent faulty
operations.
Data in memory is treated as X and Y coor-
dinates, and straight lines are drawn
between the applicable coordinates to cre-
ate consecutive line drawing. This makes it
possible to handle applications involving
the drawing of various graphics in two-
dimensional space that could not be drawn
using the existing graph components.
